Re: First Sterling Finally Running

6500 rpm that's too fast imho. I recommend placing a load on it to see how many watts you generate. Do this set up: hook up a electric generator (a low voltage motor) via a rubber band belt. Send its power to a lower voltage motor. If the generator is AC, send it thru a bridge rectifier. Measure the...

Re: Silver soldering stainless steel hot end

So NiCd batteries are in a stainless cup?
So to be safe, one must drain the battery?
What happens if one tries to burn the other parts out by tossing them into a campfire?

Re: Stirling engines with an internal spring question

Alfista, I just looked at YouTube. Neat gamma engine I saw. Big question, I saw you are able to generate over 12 volts but what about amps? A simple way to test for that is to hook your set up to another motor to act as a load. And then using two multimeters check for voltage as well as amps. Presto...

Re: Open crank horizontal engine conversion to Stirling cycle.

I think a horizontal cylinder has too much friction imho.

Re: small wood gassifier generator

Crankshaft is parts you don't need. Use a 90 degree split engine on the same pin on a flywheel.

Re: small wood gassifier generator

Btw, that Japanese Ross alpha toy that I posted about produces 1 watt of power enough for usb. That's approximately 0.5 inch bore, so an one inch bore may generate 4 watts. The airpel graphite cylinders are 1 inch bore. For a drive train there is a $65 usd toy model off eBay, use the flywheel as the...

What about a wind turbine?
An off grid wood stove CHP is technically possible but it never took off commercially.

Re: Heinrich Motor hot air engine

Flywheels are needed to supply energy for the complete rotation especially under load. For no load, I doubt the engine requires both flywheels. I recommend just trying to get it running as is. Oil everything with marvel mystery oil and hook up the higher port to a garden hose and heat it up and see ...

Re: Heinrich Motor hot air engine

Wilson, have you tried running it? You'll want to use a light oil - sewing machine oil. Typically those engines have two flywheels. Hopefully, yours doesn't require it. From what I've read a Bunsen burner should be enough to make it go. To get more power try ice water for the coolant. That could hel...

Re: Heinrich Motor hot air engine

Ian, of course I want a full size vintage hor air engine!
I like to go to old tractor and steam shows.
I have yet to see a full size water pumping hot air engine in the last 30 years. Very rare in these parts.
I do remember my father showing me one at a show when I was young. It's a vague memory.

Stirling powered toy car

I got a Meccano kit and made a toy Stirling car.
I was going to use gear reduction but I read gears rob power with friction. The rubber band drive has a nice feature as acting like a clutch as they stretch and spring back.

Re: What a difference a flue makes! +75%

Ian, from your alpha how many watts of electrical power are you able to generate?
What's the bore and stroke?
And it looks like you built it to be pressurized. How much does that increase the power by which pressure?

Re: What a difference a flue makes! +75%

A guy is selling these things on eBay. It was a long wait to convince my wife. But I finally got the Japanese Ross linkage engine. I'm very impressed with the power. It produces enough electricity to run a 6 volt motor with 100 milliamps on 90 pct alcohol. Probably the most powerful of my stirling e...
